Learn the definition of a midpoint, if you didn't already know it, and learn to find the midpoint and length of a segment on a number line.

For this unit, our reading assignment concerns the precision and accuracy of measurements. Hitting your target in Fortnite is being precise, while hitting the crit-hit spot is being accurate.

Geometry 2(A) determine the coordinates of a point that is a given fractional distance less than one from one end of a line segment to the other in one- and two-dimensional coordinate systems, including finding the midpoint

Geometry 2(B) derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines

Geometry 4(A) distinguish between undefined terms, definitions, postulates, conjectures, and theorems

Geometry 5(B) construct congruent segments, congruent angles, a segment bisector, an angle bisector, perpendicular lines, the perpendicular bisector of a line segment, and a line parallel to a given line through a point not on a line using a compass and a straightedge
